how to extract a number with decimal (dot and comma) from a string (e.g. 1,120.01) ? I have a regex but doesn\'t seem to play well with commas

preg_match(\'/([0-

The locale-aware float (%f) might be used with sscanf.

$result = sscanf($s, '%f')

That doesn't split the parts into an array though. It simply parses a float.

A regex approach:

/([0-9]{1,3}(?:,[0-9]{3})*\.[0-9]+)/
